This book was released on 2018-06-27 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report describes the process, findings, and recommendations of the second of three phases of the Future Communications Study (FCS) technology investigation conducted by NASA Glenn Research Center and ITT Advanced Engineering & Sciences Division for the Federal Aviation Administration (FAA). The FCS is a collaborative research effort between the FAA and Eurocontrol to address frequency congestion and spectrum depletion for safety critical airground communications. The goal of the technology investigation is to identify technologies that can support the longterm aeronautical mobile communication operating concept. A derived set of evaluation criteria traceable to the operating concept document is presented. An adaptation of the analytical hierarchy process is described and recommended for selecting candidates for detailed evaluation. Evaluations of a subset of technologies brought forward from the prescreening process are provided. Five of those are identified as candidates with the highest potential for continental airspace solutions in L-band (P-34, W-CDMA, LDL, B-VHF, and E-TDMA). Additional technologies are identified as best performers in the unique environments of remote/oceanic airspace in the satellite bands (Inmarsat SBB and a custom satellite solution) and the airport flight domain in C-band (802.16e). Details of the evaluation criteria, channel models, and the technology evaluations are provided in appendixes.

Book excerpt: To address emerging saturation in the VHF aeronautical bands allocated internationally for air traffic management communications, the International Civil Aviation Organization (ICAO) has requested development of a common global solution through its Aeronautical Communications Panel (ACP). In response, the Federal Aviation Administration (FAA) and Eurocontrol initiated a joint study, with the support of NASA and U.S. and European contractors, to provide major findings on alternatives and recommendations to the ICAO ACP Working Group C (WG-C). Under an FAA/Eurocontrol cooperative research and development agreement, ACP WG-C Action Plan 17 (AP-17), commonly referred to as the Future Communications Study (FCS), NASA Glenn Research Center is responsible for the investigation of potential communications technologies that support the long-term mobile communication operational concepts of the FCS. This report documents the results of the first phase of the technology assessment and recommendations referred to in the Technology Pre-Screening Task 3.1 of AP-17. The prescreening identifies potential technologies that are under development in the industry and provides an initial assessment against a harmonized set of evaluation criteria that address high level capabilities, projected maturity for the time frame for usage in aviation, and potential applicability to aviation. A wide variety of candidate technologies were evaluated from several communications service categories including: cellular telephony; IEEE-802.xx standards; public safety radio; satellite and over-the-horizon communications; custom narrowband VHF; custom wideband; and military communications.

Download or read book Aeronautical Radio Communication Systems and Networks written by Dale Stacey and published by John Wiley & Sons. This book was released on 2008-04-15 with total page 370 pages. Available in PDF, EPUB and Kindle. Book excerpt: Typically, there are over twenty radio systems on board the average commercial jet aircraft dealing with communication, navigation and surveillance functions. Very high frequency (VHF) air-to-ground communication is usually the main method of information and control exchange between pilot and air traffic control. Satellite and high frequency radio links are used to complement this system for long range or oceanic information exchanges. Other communications systems are required between the airline operation centre and the pilot and sometimes between the passengers and the ground. A comprehensive guide to current systems, networks and topologies, this book covers application requirements for communication and related radio-navigation and surveillance functions in aeronautical systems. There is also an insight into future possibilities as technologies progress and airspace operation and control scenarios change. Ideal for civil aviation authorities, airspace management providers and regulatory organizations, Aeronautical Radio Communication Systems and Networks will also appeal to aircraft and radio equipment manufacturers and university students studying aeronautical or electronic engineering. Key features: Provides a broad and concise look at the various communications systems on board a typical aircraft from a theoretical, system level and practical standpoint with worked examples and case studies throughout. Considers all types of aircraft from light aircraft to large commercial jets and specialised supersonic aircraft. Looks at existing airport radio communication infrastructure and proposals for new very high bandwidth radio applications within the airport environment. Provides a complete list of formulae for engineering design analysis and quick checks on system performance or interference analysis.

This book was released on 2014-11-19 with total page 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: The National Aeronautics and Space Administration (NASA) is investigating alternative technologies to facilitate building communication networks for future Spaceports and Ranges. This reports documents an investigation conducted from October 2002 through September 2003 of an emerging communication technology known as Ultra Wideband (UWB) communication. Contained in this report is an overview of UWB communication technology, a survey of UWB equipment vendors, and complete details of the theoretical and experimental research that was performed during this emerging communication technology investigation. The summary conclusion of this report is that UWB communication holds great promise for augmenting future Spaceport and Range communication networks through enhancing short-range, high speed, wireless communication. This enhancement is accomplished through simultaneously integrating position-aware functions with traditional communication functions. UWB technology achieves this dual-function integration through using short impulses instead of the continuous waveforms common to most wireless systems. Because short impulses are used, UWB communication links are inherently immune to most multi-path interference, and also achieve better instantaneous spectrum re-use among users. UWB modulation also provides a Low-Probability-of-Detection (LPD) waveform with selectable security. UWB systems can therefore provide fade resistant, high speed data links wherever the presence of easily detectable wireless transmissions must be avoided, such as in specialized tactical situations. Despite the many theoretical advantages that exist for UWB modulation, much anxiety commonly arises with UWB emissions because of their ultra wide bandwidths. This characteristic especially causes concern vis-à-vis possible deleterious effects to narrowband legacy systems that typically operate at low link margins, such as GPS navigation systems, which often operate with link margins of only 1 or 2 dB. Though this concern has been addressed previously in Federal regulations through the inclusion of spectral emission mask requirements for UWB emissions, not all of the technical concerns have been settled. This report further researches some of these interference concerns by investigating UWB interference to, and UWB susceptibilities from, legacy wireless systems. The summary recommendation of this report is that UWB technology appears to hold many of the key advantages needed to tackle a number of wireless systems requirements needed in the future, provided it can co-exist successfully with both legacy narrowband wireless systems, and with other UWB wireless systems. Based on the demonstrated performance seen during testing, there is ample reason to believe that UWB wireless systems will be able to coexist with most legacy wireless systems. This report is a first step in understanding and assessing UWB's applicability for supporting the communication needs of future Spaceports and Ranges.
